LED industry chain MOCVD barrier is not insurmountable

LED industry from the material equipment, epitaxial film growth, chip manufacturing and packaging and application of the entire industry chain, equipment once again become a weak link in the development of the industry. Industry experts said that China's LED industry in order to healthy and rapid development, we must work on key equipment, raw materials.

Upstream key equipment also need to rely on imports

LED a wide variety of production equipment

Key equipment almost entirely dependent on imports

According to reports, many devices in the LED production process, single crystal furnace, from the sapphire substrate for the processing of multi wire cutting, grinding and polishing equipment, MOCVD (metal organic chemical vapor deposition), annealing furnace and other equipment, and then to process IC chip and similar devices, such as lithography, etching machine cleaning machine, evaporation, etc., and finally to the solid crystal machine, wire / package with aluminum wire ball welder, sorting machine and so on many kinds. Among them, MOCVD, plasma etching machine and other high technology content of the equipment, the domestic production line all rely on imports. Only a few devices achieved domestically, such as single electric technology group forty-fifth developed cutting machine, multifunctional bonder, automatic welding machine, polishing machine, grinding wheel, laser cutting machine, all users have been used in the production line.

China Electronics Technology Group forty-eighth R & D Center Deputy Minister Hu Xiaoyu said in an interview, the domestic equipment manufacturing industry overall low level of restrictions, coupled with imported equipment and equipment of extrusion blockade of foreign patent technology, domestic LED equipment (including part of the IC chip manufacturing equipment) the overall level of backward, basically in the laboratory in terms of equipment level, production capacity, technological level, consistency, uniformity and reliability compared with the international advanced level there is a great gap. He said that in recent years, the relevant domestic research units on the LED production equipment made some attempts to make some breakthroughs in technology, such as single crystal furnace, grinding polishing machine, etc., but most did not use in the production line. Therefore, the domestic LED equipment to enter the production line is still a long way to go.

"LED industry chain in the most critical upstream equipment, the country is completely blank, but also need to import, such as MOCVD epitaxial equipment mainly from the United States, Germany and the United kingdom. In the middle reaches, the production of chip equipment now some companies have been able to do, such as the etching machine, the effect can also be used, but compared with foreign equipment there is no small gap. Crystal energy photoelectric (Jiangxi) Co., Ltd. vice president Wang Min said.

Insiders said that most of the LED equipment in the development process encountered a cost problem, most of the equipment parts imported products, while the price of equipment is much lower than foreign equipment, which makes the device's profit margins are low. At present, large LED companies enjoy the national equipment import tax exemption policy, which is very detrimental to our own R & D equipment. Wang Haiming, deputy director of the China Electricity Technology Group forty-fifth marketing department said.

Equipment development and process should be closely integrated

Complete cloning of photovoltaic devices do not work

Process development to meet the needs

Domestic equipment has played a big role in the solar photovoltaic industry chain, domestic LED equipment can also make up the missing link in the LED industry chain? Hu Xiaoyu said, LED industry and the solar energy industry has a lot of similarities, but there are a lot of difference, the domestic LED equipment if the complete cloning of photovoltaic equipment is certainly not feasible. In all photovoltaic devices, and no one kind of equipment, like MOCVD, in the entire LED production equipment investment accounted for such a large proportion. Domestic LED equipment manufacturers must start to break through the MOCVD equipment, in order to gradually advance the road and the road after the continuous expansion of process equipment, and ultimately realize the whole industry chain of all equipment localization. MOCVD equipment technical threshold is very high, need to overcome a lot of difficulties, put a lot of manpower, material resources, financial resources, integration of various resources, but this is not insurmountable.

China Electronic Equipment Industry Association Secretary General Jin Cunzhong said, LED unlike photovoltaic equipment, it requires higher technology and technology. At present, many domestic manufacturers are weak, production process control and poor development level is low, the key parts caused by the domestic stability and reliability of the equipment is not up to the requirements, resulting in domestic production enterprises even spend big price to buy foreign equipment. Therefore, in order to make a difference in the domestic LED industry in the process of development, we must do a good job in the stability and consistency.

Wang Haiming said, in the production of LED, the process needs to break through the MOCVD, the device is the key equipment of chip manufacturing equipment, the long-term dependence on imports, a single price in 30 million yuan, restrict the development of China's LED chip manufacturing; demand of high speed automatic packaging equipment after the road wire bonding machine the larger, home to batch equipment.

Wang Min said, MOCVD is not insurmountable, the country is able to do it, but it is difficult to achieve a high level, at this stage is not the ability. He stressed that the MOCVD production equipment can introduce foreign technology, if completely rely on their own research and development will be slow.

LED development today, restricting the promotion of a large area of the factors or the level of the development of the equipment industry, the data show that the depreciation of the LED equipment industry accounted for the cost of 1/3. Therefore, if the majority of LED devices to achieve localization, it is possible to make a significant decline in the cost of LED production, so that LED into millions of households.

Wang Min said that the reason why the domestic equipment is not on the production line, compared with the overall level of the domestic equipment industry is relatively low. China's equipment industry
